(b) Pilotage fees shall be 350 for all vessels, plus an additional fee of $3 per foot of draft or fraction thereof for all vessels over 12 feet. Notwithstanding the above, when the services of a pilot are actually required for a deep draft vessel the minimum charge shall be $100.

(c) Other fees shall be:

(1) moving vessels in harbor: $100 each move;

(2) anchoring: $100 each anchoring;

(3) if in the performance of his duties a pilot is detained by any vessel, a charge shall be made for such detention at the rate of $75 per hour or fraction thereof;

(4) in instances where a pilot is required to accompany a vessel beyond the normal pilot station (one-half mile beyond Whatel Rock Buoy) for any purpose, including interisland pilotage, a charge shall be made at the rate of $50 per hour, and the vessel shall be responsible for the return of the pilot to the port of embarkation:

(5) the charges provided for waiting shall be applicable only when the services of a pilot have been requested and confirmed, and only when the services of a pilot are actually required;

(6) a pilotage fee of $10 to or from the harbor shall be assessed against all light draft vessels as defined in these regulations if the services of a pilot are not required;

(7) Yachts of less than 12-foot draft shall be exempt from pilot fees unless the services are actually performed; yachts of over 12-foot draft shall be exempt from one-half the pilot fees unless actual pilot service is rendered;

(8) pilotage fees for vessels with tows shall be based on the vessel having the deepest draft, and the charge shall be 50% of that charge for each additional vessel or vessels as long as the vessels remain connected together. If the vessels are separated, pilot fees shall be based on the draft of each unit.
